SRQ041 Prospex Speedtimer World Athletics Championships Oregon22 Limited Edition. Designed for
those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with
technological excellence and style. Celebrating Seiko’s first precision chronographs, developed
for international sporting competitions in 1964, as well as its 1969 introduction of the world’s first
automatic chronograph, this exceptional watch provides chronograph measurement of up to 30
minutes of elapsed time in 1/8-second increments. Produced in a limited edition of 400 for the
World Athletics Championship, with a special embossed logo for the competition and the serial
number engraved on each caseback to show its place in a controlled-production run, this unique
design features a low-reflection black dial patterned to recall the running track at the legendary
Hayward Field, site of WCH Oregon 22. The contrasting subdials, LumiBrite hands and markers,
and yellow chronograph hand provide enhanced legibility. Visible through the screwdown, seethrough
caseback, the 34-jewel automatic movement beats at a frequency of 28,800 vibrations
per hour, with a power reserve of approximately 45 hours and manual winding capability. The
proprietary 8R46 movement includes a column wheel and vertical clutch mechanism allowing for
smooth, stutter-free movement of the chronograph hand while providing longer wear and
efficiency, and improving maintenance of the power reserve during chronograph operation.
Crafted of stainless steel with super-hard coating, specially designed pushers and crown for ease
of use, tri-fold push button release clasp, and dual curved sapphire crystal with anti-reflective
coating on the inner surface, this extraordinary timepiece also includes an additional black leather
strap, and is packaged in a Limited Edition collectors’ box. 10 bar, 100M Water Resistant
